Rockford Lead Service Lines: What the City Inventory Shows

In August 2024 the City of Rockford said it had assessed every service line in its water system and counted 14,085 lead lines, 11,534 non-lead lines, 452 galvanized lines and 29,304 lines of unknown material. The Illinois Lead Service Line Replacement and Notification Act is the reason those counts exist. The City's online map is how a buyer can look up a single address before signing a contract. Gambino Realtors has been in business since 1923 and is based in Rockford. This guide covers what the Act requires of the City, what the City publishes, and what you can ask for while you browse the Rockford real estate listings.

What the Illinois Act Requires of the Water Supplier

The law is Public Act 102-0613, which says it may be referred to as the Lead Service Line Replacement and Notification Act. The Illinois EPA says it took effect January 1, 2022. It replaced the older inventory rules, and the working text sits at 415 ILCS 5/17.12 in the Environmental Protection Act. The Act is aimed at the owner or operator of a community water supply. In Rockford that is the City's Water Division. The Division describes itself as serving approximately 55,000 water customers.

The Act has four jobs. It requires a water supplier to build and maintain a service line material inventory. It requires a replacement plan. It requires notice to the people in a building before work on a lead line or on a water main with lead lines attached. And it bans partial lead service line replacements, with exceptions. Notice what is missing from that list. Nothing in the Act text mentions the sale of a home, a seller's duty or a buyer's right. The words sale, seller, buyer, purchase, transfer and closing do not appear in the section in any real estate sense. The Act regulates the water supplier. It does not add a step to a real estate closing.

Start with the terms, because the inventory only makes sense with them. A "service line" is the piping that runs from the water main to the building plumbing at the first shut-off valve, or 18 inches inside the building, whichever is shorter. A "lead service line" is a line made of lead, or a line connected to a lead pigtail, a lead gooseneck or another lead fitting. A "suspected lead service line" is one the supplier finds more likely than not to be lead after it has worked through its records and inspections. That last category matters for a buyer. A line can sit on the City's list as suspected without anyone having dug it up.

The dates are fixed in the statute. A supplier had to develop an initial inventory by April 15, 2022. It had to submit an updated inventory electronically by April 15, 2023. It had to deliver a complete inventory to the Illinois EPA no later than April 15, 2024, or when federal law required, whichever came first. The complete inventory has to report the composition of all service lines in the system. A supplier that could not meet the final date could apply for an extension at least three months ahead, and the Agency set criteria for granting one. Rockford stated its counts publicly in August 2024. This guide could not read Rockford's filed inventory itself, so it does not say whether the City asked for an extension.

The inventory has required contents. It must identify the total number of service lines, the material of each line, the number of suspected lead lines newly identified since the last submission, and the number of suspected or known lead lines replaced since then, along with the material that replaced each one. The supplier also has to identify, to the best of its ability, the material on the customer's side and on its own side of the curb box, meter or other dividing line. That split is the one a buyer cares about. The public piece and the private piece of the same line can be different materials.

The Act also tells the supplier how to find out. It must prioritize inspections of high-risk areas and facilities such as preschools, day care centers, parks, playgrounds, hospitals and clinics. It must review historical records, such as construction logs or cards, as-built drawings, purchase orders and subdivision plans. It must visually inspect and document a line whenever it is doing distribution system maintenance. It must identify any period when connections were primarily lead, if that is known or suspected. And it must talk to the employees, contractors and plumbers who worked on those lines. The Act says nothing requires a line to be unearthed for the sole purpose of inventorying. So a "suspected" label can rest on paper records and a pattern, not a shovel.

Two more rules shape what you see. If a homeowner refuses the supplier access to the inside of a building to identify a line, the supplier keeps a record of the refusal. It must then attempt to identify that line as a suspected lead service line unless documentation shows otherwise. And lines that are physically disconnected from a water main are outside the inventory duty. A supplier also has to post a copy of its most recently submitted inventory on its website, or ask the Illinois EPA to post it.

What Rockford Has Published and Where It Sits Now

The City's Water Division runs a page titled Lead and Drinking Water. It says lead is not present in Rockford's source water, which is groundwater, and not in its treated drinking water. It adds the condition that matters here. If a building has a water service line made of lead, lead can enter the drinking water through corrosion of plumbing materials. In other words, the City places the risk in the line between the main and the house, not in what comes out of the ground.

The page points to three tools. The first is an interactive Lead Service Line Identification map. A customer clicks the water drop on the map and gets information about that service, with information on both public and private service lines. The second is a digital service line material identification survey, reached by a QR code, which the City uses to learn the material of private service lines. The third is a free annual lead test. The Division delivers test kits to households, and you request one through Water Quality at 779-348-7151.

Now the numbers, with their dates. WIFR reported on August 19, 2024 that the City had assessed every service line in its distribution system. Add them and you get 55,375 lines, which sits in the same range as the Division's own description of about 55,000 customers. The City's page gives no current count, and counts move as lines are replaced and unknowns are identified. Treat the 2024 breakdown as a snapshot, not today's total.

The galvanized number deserves a sentence. The statute explains why. A replacement plan must cover each galvanized line that is or was connected downstream to lead piping. The Illinois EPA's own summary page notes that from 2023 the old "Galvanized" field was split into "Galvanized Requires Replacement" and "Galvanized not Requiring Replacement." A galvanized line that is or has ever been connected downstream to lead falls in the first group.

The 29,304 unknowns are the largest group in that snapshot, and the City says what it wants done about them. According to the same report, properties with lead or galvanized lines are added to a replacement list and the City said it would replace those lines at no cost to residents.

Replacement is paid for through the Illinois EPA's Public Water Supply Loan Program, a State Revolving Fund, according to the City page. The City also encourages voluntary full replacement on both public and private property, from the water main to the meter. Per the City, if an owner meets specific requirements and agrees to pay for the private-side work, the Water Division coordinates and replaces the public-space portion at the same time. Field Services handles those questions at 779-348-7152. The Act's own pace is a separate matter. Its replacement schedule depends on the count in the supplier's final inventory. A supplier reporting more than 9,999 but fewer than 99,999 lead lines must replace at an annual rate of no less than 3 percent of that count, with a timeline of up to 34 years from the date of its final plan. If the 2024 count of 14,085 were the final figure, 3 percent would be about 423 lines a year. That is arithmetic on a snapshot, not a City statement. The filed final inventory and plan fix the real number, and the Agency may grant a timeline extension of up to 20 percent.

What a Buyer Can Ask, Look Up and Put in Writing

Begin with the address lookup. The City's map is the first place a buyer can see how the Division has classified a service. The classification will be one of the four you saw above: lead, non-lead, galvanized or unknown. Take a screenshot with the date on it. Counts change as lines are replaced, so a dated capture shows what the map said when you made your decision. The map is also where the public side and the private side of a line are described, which is the split the statute asks the supplier to identify.

Then read the seller's disclosure report. The Illinois Residential Real Property Disclosure Act sets the form in 765 ILCS 77/35, and item 17 asks the seller whether the seller is aware of unsafe concentrations of or unsafe conditions relating to lead paint, lead water pipes, lead plumbing pipes or lead in the soil on the premises. Item 9 asks about material defects in the plumbing system. Item 11 asks about unsafe conditions in the drinking water. Two details in the form decide how much weight to put on a "no." First, "aware" is defined as actual notice or actual knowledge without any specific investigation or inquiry. A seller does not have to go find out what the pipe is made of. Second, the form says it is not a warranty. A seller who has never seen the pipe can truthfully answer "no" to item 17 while the City map shows the line as lead. The report is a statement of what the seller knows. The map is a statement of what the City has recorded. They answer different questions, so read both. For the rest of the form, see the guide to the Illinois seller disclosure report in Rockford.

Keep lead paint and lead pipes apart in your head. Item 17 groups them on one line, but they are different problems with different rules. The federal Lead-Based Paint Disclosure Rule is about paint. The EPA says lead-based paint was banned for use in homes in 1978, that it is still present in millions of homes, and that it is not a hazard when it is in good condition. A service line is a pipe between the main and the building. The paint rule and the pipe inventory are separate documents with separate sources. The City's page ties the risk to the material of the service line, so the address lookup is the right test for a pipe.

A home inspection is where the physical check happens. The statute defines the service line to the first shut-off valve, so the part inside the building is within the same definition as the part under the yard. Rock River Current described the checks the City recommends on the pipe between the point where it enters the house and the shut-off valve. Scratch the pipe with a flathead screwdriver. If a shiny, silver surface shows under the scratch, the City says it is lead. A magnet will not stick to a lead pipe. Tapping a lead pipe with a penny gives a dull sound. Those are the City's home checks as reported, and a licensed inspector or plumber is the person to confirm them. The inventory records the customer's side and the supplier's side of the line separately, so a visible piece inside the house does not describe the whole run. Ask the inspector to write down what was visible and where. The guide to what the inspector checks in a Rockford home covers the rest of the walk-through.

Here is a short list of questions that fit this topic and that the sources support.

• What does the City's identification map show for this address, and what is the date of my screenshot?
• Is the line listed as lead, galvanized, non-lead or unknown?
• Has the seller received a notice or letter from the City about the line, or about planned replacement work in the area?
• Has any part of the line been replaced, and by whom? A partial replacement is prohibited under the Act, with exceptions such as emergency repair.
• If the line is lead or galvanized, is the address on the City's replacement list?
• If the material is unknown, can the seller complete the City's identification survey before closing?

The notice rules give the third question its footing. When a supplier identifies a lead service line, it must attempt to notify the building owner and all occupants within 15 days, or as soon as reasonably possible. Before a planned replacement, it must mail the owner a request for access at least 45 days ahead, then try posting the request at the entrance if there is no reply in 15 days. A seller may therefore hold paper that tells you something about the line. Ask to see it. It is a document, not a rumor.

The private-side piece needs a plain reading. The Act prohibits partial lead service line replacements. When a supplier replaces a lead line, the statute says it must replace the entire line, including the part on private property and the part within the building plumbing at the first shut-off valve. There is an exception for emergency repair. If the owner cannot be reached or refuses access during an emergency repair, the supplier may do a partial replacement. It must then give written notice, provide a filter certified to NSF/ANSI Standards 53 and 42 for at least one fixture, and replace the remainder within 30 days, or 120 days for weather or circumstances beyond its control. It must also record the remaining lead line in its inventory. A line that looks half new may therefore be explained by an emergency repair, and the question to ask is whether the remainder was finished.

There is also a rule about work an owner does. If the owner of a building intends to replace a portion of a lead line, or of a galvanized line that is or was connected downstream to lead, the owner must give the supplier notice at least 45 days before starting. A buyer who plans a plumbing renovation should treat that as a pre-work step and not discover it halfway through. The statute otherwise prohibits partial replacement by owners. If you are thinking of a renovation, a conversation with the Water Division before a plumber digs is the clean path. The guide to moving to Rockford lists the City's utility contacts that follow the closing.

What if you buy a home with a lead line and the line is on the replacement list? The City says it will contact customers as it works an area, and the Act gives a supplier the duty to request access by mail. If the owner refuses to sign or does not respond, the supplier must notify the Department in writing within 15 working days. The City mails these requests to the building owner, so the owner of record is the person who receives them. The guide to the final water bill and closing in Rockford explains the City's closing steps for the water account.

For a house you already own or are about to own, the City lists lead-safe habits. Flush the kitchen tap on cold for one to two minutes before using water for drinking or cooking. Clean the faucet aerators. Consider a home water treatment device that meets National Sanitation Foundation standards. And test the water in houses with older plumbing. The City says it offers free annual lead tests, and its corrosion control relies on naturally hard water with a neutral pH and a food-grade polyphosphate treatment under the Lead and Copper Rule. The City says it is in full compliance with that rule and on a reduced monitoring schedule every three years. Those are the City's statements about its system. The service line on your property is a separate question that only the address lookup, the inspection and the City's records can answer.

If the buyer is renting out the house afterward, the Act has one more line. An owner of a nonresidential building or a residence operated as rental property who refuses a complete lead service line replacement is responsible for installing and maintaining certified point-of-use filters at the fixtures used for drinking, food preparation and making baby formula, until the line is replaced. Anyone who is buying to rent should read that paragraph of the statute with their attorney.

Bottom Line

The Illinois Act puts the inventory duty on the water supplier, and Rockford's snapshot from 2024 shows 14,085 lead lines, 452 galvanized lines and 29,304 unknowns out of a total near 55,000. The Act does not put a lead-pipe step into a home sale, so the work falls to you. Look up the address on the City's map and keep a dated copy. Read items 9, 11 and 17 of the seller's disclosure report with the "aware" definition in mind. Ask for any City notice the seller received. Have an inspector write down the visible pipe material and its location. Then call the Water Division for anything the map leaves open. Gambino Realtors has been in business in Rockford since 1923, and these are the steps to take before you make an offer on anything in the Rockford real estate listings. For the wider set of Illinois buyer guides, see the Illinois Real Estate Guide.

That is the whole picture of the rules and the City's own tools. For anything specific to a property, the City's Water Division and your attorney are the right voices. Here are eight short answers to the questions a buyer would reasonably put to the City or the seller.
